頻帶的英文：
frequency range
bandwidth

參考例句：
  • (also waveband)radio range of wavelengths within specified limits
    波段頻帶
  • Broad band beam antenna
    寬頻帶定向天線
  • Frequency discriminator pass Band
    鑒頻器通頻帶
  • The difference, expressed in hertz, between the two limiting frequencies of a band
    一個頻帶的上下界頻率之差,單位用赫茲表示。
  • This reduces gain but widens the amplifier's passband.
    這方法降低了增益，但加寬了放大器的通頻帶。
  • Another attribute is the flux or radiant power that can be delivered in that narrow frequency band
    另一個性質(zhì)就是在這樣窄的頻帶內(nèi)可以給出很高的光通量或輻射功率。
frequency是什么意思：
n. 發(fā)生率，頻繁，頻率
  • W is the radian frequency deviation from the center frequency
    △W是角頻率與中心頻率的偏離值。
  • The frequency inverters has a function of variable voltage and variable frequency.
    頻率逆變器具有變壓、變頻功能。
  • Accidents are happening with increasing frequency.
    事故發(fā)生得越來越頻繁。
range是什么意思：
n. 一系列；排，列；山脈；類別；幅度；等級；范圍；射程；射擊場；牧區(qū)；爐灶
v. 排列；歸類于；射程達到；漫游；延伸；變化；涉及
  • the range of the nightingale
    夜鶯的生長區(qū)
  • range the hills, countryside, etc
    漫游山地、 鄉(xiāng)村等.
  • range crane fly
    牧場大蚊
bandwidth是什么意思：
帶寬 ; (是指網(wǎng)絡(luò)上每秒能通過的最大數(shù)據(jù)量。例如T1線路擁有1.544MBPS的頻寬)
n.精力
  • Bandwidth traditionally was not up to that of wired networks.
    傳統(tǒng)上帶寬達不到有線網(wǎng)絡(luò)的帶寬。
  • First, bandwidth traditionally was not up to that of wired networks.
    第一，傳統(tǒng)上帶寬達不到有線網(wǎng)絡(luò)的帶寬。
  • Halving the repeater spacing made it possible to quadruple the bandwidth.
    將增音機間距減少一半，能使寬帶增加3倍。
